Description

A high-altitude suspension insulator disassembly mechanism and automatic replacement device

technical field

The invention relates to the technical field of repair and maintenance of electric power facilities, in particular to a disassembly and assembly mechanism and an automatic replacement device of a high-altitude suspension insulator.

Background technique

In the erection of high-voltage lines, many lines are erected at high altitudes. High-altitude erected lines usually require insulators or insulator strings to fix high-voltage lines on tension towers or linear towers. The connection structure, that is, the plug-in terminal 1001 on the front end of the insulator and the rear end of the adjacent insulator, as shown in Figure 1 and Figure 2, when the insulator needs to be replaced, it is necessary to turn the insulator adjacent to the insulator to be replaced by a certain angle. , that is, rotate the notch 1002 on it by 180°, so that the notch 1002 faces upwards, so that the plug end 1001 of the insulator to be replaced can be taken out from the notch 1002 .

At present, when the suspension insulator is replaced, it can only be replaced by the traditional method, that is, manual operation at high altitude, disassembling and assembling the insulator by using a mechanical screw and a manual hydraulic screw, has the following defects:

1. Ergonomics: The rated load of single-piece insulators for UHV DC lines is generally about 550kN, the weight is about 25kg, and the working space is limited (the gap between strings is about 1.0 to 1.3m). When replacing the tension-resistant single-piece insulator of UHV DC line, the screw (hydraulic or mechanical) + closed clamp operation method is generally used at present. It is extremely laborious for aerial workers to tighten the screw and disassemble and assemble the insulator, and two people are required to cooperate. , poor coordination of human-machine functions.

2. Personal safety risks from object strikes and high-altitude falling: When replacing tension-resistant single-piece insulators for ±800kV and ±500kV UHV DC lines, due to the large distance between insulator strings (the gap between strings is about 1.0 to 1.3m), it is necessary to replace the string on the replacement string. However, the relevant regulations and operating standards stipulate that "it is strictly forbidden for the operator to sit on the string to be replaced to disassemble and assemble the insulator". If the operation error causes the insulator to fall off the string, fall from high altitude and hit objects, it will threaten personal safety.

3. Safety of live work: According to the provisions and provisions of Chapter VII of GB50790. The combined clearance of two-person operation is 10200mm-15*170mm=7650mm, and the combined clearance of single-person operation is 8840mm, the higher the risk rate of two-person operation. The longer the operation time, the higher the probability of outgoing line power frequency, operation and lightning overvoltage amplitude, and the higher the danger rate.

4. Reduce the weight of the tool and shorten the operation time: the traditional construction method, the fixture is 12kg, the lead screw weighs 6 to 9kg, the assembly and disassembly steps are complicated, the labor intensity is high, and the replacement time is long. For example, on average, each group (4 people) can replace a maximum of 3 tablets per day.

5. The construction method is backward, the degree of automation is low, the technological innovation is insufficient, and the economy is poor: At present, the replacement of single-piece insulators for UHV DC lines is traditional manual tools, which are low in efficiency, high in operation risk, limited in maintenance ability, and poor in economy. It is difficult to adapt to the current high-quality development requirements of power enterprises.

Therefore, it is necessary to develop a high-altitude suspension insulator disassembly mechanism and an automatic replacement device based on the risk and difficulty of the replacement of the tension-resistant single-piece insulator in the UHV DC line.
